Chapter 458: First Meeting with Mr. Yang

No matter how other countries are struggling to restart China's manned spaceflight and lunar exploration projects, Xu Chuan is immersed in his own world.

From the perspective of quantum chemistry, the strong antimagnetic mechanism in KL-66 material is explained.

It has to be said that when the traditional condensed matter theory loses its effect, quantum theory plays an unexpected role at this time.

However, for now, this is just a new path, and Xu Chuan is not sure whether it can be done.

Late at night, in Beihai Hotel, Xu Chuan sorted out the manuscripts on the table, then got up and washed up.

If it were normal, he would probably continue to stay up for a while and study it.

However, today I have promised Mr. Pan to go to Peking University to chat with him tomorrow, so I just rest early.

After all, the old man's sleep time is short, and the morning should be the time when he is more energetic.

The next day, early in the morning.

Xu Chuan got up early, moved his body and had breakfast before going to Peking University.

After successfully passing the security and finding the professor's residential area, Academician Pan Deming was stretching his muscles in the community.

"Good morning, Mr. Pan." After watching for a while, Xu Chuan stepped forward and greeted him with a smile.

Hearing the voice, the old academician Pan Deming, who was practicing Tai Chi, turned his head and looked over, with a smile on his face: "Good morning, have you had breakfast?"

"I have eaten, how is your health recovery, Mr. Pan?" Xu Chuan smiled and gave the tea leaves he brought to the old academician in front of him, and asked with concern.

"Tea?"

Pan Deming took the box curiously, looked at it, and smelled it, and then smiled and said: "This tea is of good quality, where did you get it from?"

Xu Chuan smiled and said: "The elder gave it to me, I don't know what kind it is. He asked Qin Dichang to bring it to me during the meeting yesterday. Thinking that you don't lack anything to eat and drink, I borrowed a box to offer you."

Hearing this, the old academician Pan Deming was slightly stunned, and then smiled and said: "Then feelings are good things, I will accept it."

Xu Chuan smiled and said: "As long as Mr. Pan likes it, it's fine . "

Pan Deming laughed and said, "Speaking of tea, I was able to get two boxes of good tea from Qin Zhuo two years ago. Later, maybe I asked for too much, so he hid it from me."

"Come on, come in and sit down first. Do you have time today? Have lunch before leaving? Have a drink with me at noon?"

Xu Chuan smiled and said, "You have to take care of your health. Try to drink less."

Pan Deming took Xu Chuan into the room and smiled, "Well, it's rare to be happy, so don't say such things."

After a slight pause, he took "I heard that we are going to build a large particle collider?"

Xu Chuan nodded and said, "Yes, it is indeed a request. The relevant instructions have been issued. There will be a related discussion meeting at the Science and Technology Bureau next Thursday."

Pan Deming smiled and looked at Xu Chuan and said, "That's good. It is necessary to build such scientific facilities."

"But can you handle it? There is a manned space project, a collider, and the management of the Xinghai Research Institute. Do you have enough energy?"

Xu Chuan smiled and said, "It depends on how you use it."

Paused , he continued: "For me, management work has never been the focus. I prefer to lead the team to solve technical problems."

"Just like when studying controlled nuclear fusion, the daily management work is basically handled by Peng Hongxi and Gao Hongming. I just need to concentrate on overcoming technical problems."

Pan Deming smiled and said, "You really don't care about these things at all. You can retire from the position of chief designer and person in charge of controlled nuclear fusion."

As he said, he looked at Xu Chuan, smacked his lips, and shook his head with a smile.

To be honest, if someone else is given a position like the chief designer and person in charge of controlled nuclear fusion, even if he is given it, he may not have such a strong determination to retire directly.

After all, there will be development in the direction of second-generation controlled nuclear fusion and fusion energy companies in the future. As long as he sits in that position, his right to speak is unshakable.

But after the successful ignition of the demonstration reactor, the young man in front of him turned around and left as if he had completed his mission.

Xu Chuan smiled and said, "What I do is actually just what a scholar and a researcher should do."

Pan Deming smiled and asked curiously, "Speaking of which, do you still have time and energy to study mathematics?"

"Now you are developing in various other fields and are almost turning into an applied scholar. Are you still doing theoretical research?"

Hearing this question, Xu Chuan smiled and said, "Of course, application and theory are parallel tracks. No matter which one is separated, the scientific research train will be derailed."

"In the past two years, I did less research because of the controlled nuclear fusion project, but I still have to pick it up."

After a pause, he continued, "In fact, I have been studying some theoretical things recently, but there has not been much progress so far."

Hearing this, Pan Deming looked over curiously and asked, "What aspect? Mathematics or physics?"

"Both aspects, mainly in the field of strongly correlated electron systems."

Xu Chuan smiled and replied, "When I was studying the KL-66 material in South Korea before, I made some unexpected discoveries. I am trying to explain it through mathematics."

"If it succeeds, the theory of strongly correlated electron systems should be able to achieve some breakthroughs. However, it is still being explored and it will be difficult to achieve a breakthrough."

For the old academician in front of him, he didn't mind revealing his research direction and scope.

After all, if he can no longer be trusted, there will be no trustworthy person in this world.

Hearing this, Pan Deming looked a little moved. He said: "This should be a worldwide problem. The condensed matter physics community has also been studying it for many years."

Xu Chuan nodded and said, "Well, you can put it this way."

"This research is actually mainly for superconducting materials. Subsequent research in aerospace engineering and controllable nuclear fusion will require the use of superconducting materials with high critical magnetic fields."

"If there is a breakthrough in this theory, it may be possible to increase the critical magnetic field of superconducting materials by an order of magnitude."

Pan Deming thought for a while and said: "I don't know much about strong correlation systems, but maybe you can talk to Yang Zhenhuan? His research in condensed matter physics is still very unique."

Xu Chuan smiled and said: "Old Yang will be a hundred years old next year, and he is already ninety-nine this year. It is not appropriate to nag him again."

Hearing this, the old academician Pan Deming sighed and said: "There are many scholars in the country, and there are also many engaged in mathematics and condensed matter physics, but only a few can reach the top of the world. Otherwise, there will be no one to talk to." Talk about the problem.”

"Since you, the gap between top scholars has been too serious. No, it should be said that you have brought domestic mathematical physics to a whole new level, which is why this problem has arisen."

The two seven-millennium problems can be said to be a towering mountain that is unattainable for the Chinese mathematics community.

Looking at the young mathematician in front of me at this level, looking at the entire country of China, Mr. Qiu, who returned from the United States, is probably the only one alive today who can enter this field.

Maybe Mr. Yang, who is engaged in physics, can count half of it, but after all, he is not a person in mathematics.

Others, such as Zhang Yitang, the golden generation of Peking University, Li Jun of Fudan University, and others, are still far behind compared to the person in front of me and Mr. Qiu.

Xu Chuan smiled and was about to open his mouth to speak. In the living room, two old people walked in accompanied by a middle-aged woman.

Seeing the person coming, Xu Chuan was stunned for a moment, with a trace of surprise in his eyes.

The old man walking in front was Mr. Yang, whom he and Academician Pan were chatting with just now, and the middle-aged woman next to him was undoubtedly his ex-wife, Ms. Weng, and she was holding a fruit basket in her hand. .

And standing a little behind was Mr. Qiu.

These two people came together, which really surprised Xu Chuan.

After all, this is Peking University, and both Qiu and Yang are in Shuimu.

Of course, it's not that far apart, just a street away, and you can just stroll there.

In the living room, Mr. Qiu, who was walking behind, had sharp eyes. He immediately saw Xu Chuan sitting on the sofa and greeted him with a smile: "Hey, Academician Xu, what a coincidence. I didn't expect you to be here." Here too?"

Hearing this voice, Mr. Yang, who was walking ahead, squinted his eyes and recognized Xu Chuan.

Xu Chuan stood up with a smile and said hello to the two old men: "Mr. Qiu, Mr. Yang, I didn't expect to meet you two here."

Qiu Chengtong smiled and said: "It's not the old guy Pan Deming. He was lying there in the hospital for more than a month some time ago, causing people to worry. After he was discharged from the hospital, Lao Yang and I came over to take a look. Don't let this old guy leave. Ahead of us."

"But looking at him today, he should be recovering well."

For Qiu, although he has an incomprehensible relationship with the Department of Mathematics of Peking University, that is another matter and does not affect his friendship with Academician Pan.

After all, the two are almost the same generation and can be said to have been friends for many years.

Hearing this, Pan Deming suddenly blew his beard and glared, and looked over: "You old guy, how can you talk? I won't leave even if you leave!"

Qiu Chengtong ignored him, looked at Xu Chuan with a smile, and asked, "Speaking of which, why are you here?"

Hearing the sharp 'quarrel' between Qiu Chengtong and Pan Deming, Xu Chuan twitched the corner of his mouth a few times and replied: "Didn't Shuimu hold a meeting on the manned aerospace project yesterday? I came here to attend the meeting. Then he Come and sit."

Qiu Chengtong raised his eyebrows and said with a smile: "It seems that you and this old guy have known each other quite early."

Xu Chuan coughed lightly and said, "We have indeed known each other for a while."

On the side, Mr. Yang sat down with the support of Ms. Weng and looked Xu Chuan up and down.

This was the first time the two met, and they had never met before.

After all, when Xu Chuan came back in 2018, he was already 96 years old and had already retired.

But they must know each other, at least they know each other.

After staring at Xu Chuan for a while, Mr. Yang sighed: "The first time I heard your name, it was from astronomy."

"If I remember correctly, it seems to have been 15 years. At that time, your observations and calculations of Betelgeuse shocked the entire astronomy and astrophysics world."

"I didn't expect that only three years later, you would win the Nobel Prize in Physics and solve the problem of controllable nuclear fusion technology. Your future will be formidable."

Xu Chuan smiled and said, "I've always wanted to visit you, but I'm too busy at work and couldn't spare the time."

Mr. Yang waved his hand and said: "I originally planned to chat with you at the collider seminar a week later, but I didn't expect to meet you in advance today. It is considered a fate."

After a slight pause, he glanced at Xu Chuan and asked curiously: "How is your research on sterile neutrinos and dark matter going?"

Xu Chuan thought for a moment and said: "Research in this area can only be said to have directions and ideas. For specific situations, we need to conduct experiments with collider, conduct calculations, collect data and analyze it."

"Are you sure?" Mr. Yang asked.

Xu Chuan smiled and said: "When it comes to research, no one dares to say that they are 100% sure of doing it until the truth has settled."

After a pause, he looked at Academician Yang and said with a smile: "But I am still more or less certain, but I don't know how many difficulties we will encounter in the process."

Hearing this, Mr. Yang stared at him for a while and was silent for a long time before speaking: "In the past few decades, whenever the country discusses the construction of a large strong particle collider, I have publicly stood up and written articles. Those who oppose it also directly delay the construction of the collider.”

"I think it is totally not worth spending 200 billion to build a collider. After all, we are still in the process of development and there are more places where money is needed."

"And we lack high-level physics talents. The number is not even 1% of the world's physics researchers. Even if the collider is built, how many of us will be able to make full use of it?"

"Including 2016, even though the country was able to build it at that time, I still think it is a project that wastes people and money."

"For this reason, I almost fell out with the entire domestic physics field."

"I know that my colleagues are very dissatisfied with me and say that I want to shut down their industry. But this collider will cost 200 billion, and the follow-up will be even more. I don't think I can accept this. "

Hearing this, Xu Chuan smiled and asked, "So Mr. Yang wants to persuade me to take it easy today?"

He knew that this man had always been opposed to building a collider, but he didn't expect that this old gentleman seemed to want to convince him when they met for the first time today?
